Along with the Dynamic Glass and Dynamic Tank, Dynamic Valve makes up the multi-block that is the Dynamic Tank, a fluid storage structure that can hold a single type of fluid, unlike Railcraft Tanks however they have no size constraints in configuration similar to Xycraft Tanks, as such the tank can be placed in a 6x4x5 configuration, however it still have a minimum limit that it has to be 3x3x3 and max of 12x12x12 anything in between is still accepted as a multiblock however. Also, as the name implies this acts as the window to the dynamic tank and can also be use as a decorative block.
